From Sand to Stone = Sandstone; A Remarkable Transformation
A classic example of this is the conversion of organic matter (peaty material, dead critters) to the various components of oil and gas (hydrocarbons). The optimum temp for this process is between 80 o-120 o C, which in many places means the sediments have been buried beneath 3 km or more of rock.

Sandstone: Types, Formation, Classification, Uses – Geology In
Sandstone is a sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. It is one of the most common sedimentary rocks, making up about 20–25% of all sedimentary rocks. Sandstone is a clastic sedimentary rock, meaning it's formed from cemented pieces of other rocks and minerals.

Sandstone
Sandstones are a type of clastic (terrigenous) sedimentary rocks deriving, as the name suggest, from the consolidation of sandy sediments. Sand consists of clastic particles produced by the erosion of pre-existing rocks with grain size comprised between 0.0625 and 2 mm. The upper boundary of 2 mm arbitrarily separates sand (and sandstones) from the coarser gravel and …
Sand and gravel resources
The mode of deposition of sand and gravel is most commonly derived from the action of water in rivers, lakes or oceans. The water velocity and turbulence, combined with the settling rate of the particles, determine the movement of sand and gravels by suspension (sweeping free of the stream bed), saltation (bouncing), or traction (rolling, sliding or tumbling).
